Primary Fermentation (# of Days & Temp): 13 (~66 deg)

6 lbs Dark DME

Steeped 45 min:
1 lb 60L Crystal
1 lb Maris Otter
.50 lb roasted barley
.25 lb chocolate malt
.25 flaked oats

1 oz Norther Brewer (60 min)
.5 oz Tettnang (60 min)
1 oz Fuggles (20 min)

8 oz lactose (15 min)
1 tsp Irish moss (10 min)
.75 cup special dark cocoa (5 min)

Looks like a tasty beer, You might up the oats for a little more mouth feel, but that is just me i like a thicker stout. Also it may do a little better the longer it ages.

Cheers

I agree with wop31, boost the oats. I would suggest using light DME, since you don't know what makes the malt extract dark. The roasted and chocolate malts will make the beer black anyway, you don't need extra color, or flavor, from the DME.

If you steep at 155F, you'll effectively be doing a mini-mash and get more out of the oats, C60L and chocolate.
